Remarks.

This species resembles the Oriental species O. srilankiensis Werner & Peters 2018 (Sri Lanka) in having the body robust; antennal scape red-brown, rest of antenna black; flagellum about 1.3 × as long as head width; pronotum about 0.5 × as long as mesonotum; pronotum pentagonal, with broadest part before midlength; propodeum large; forewing hyaline; marginal vein medium; ovipositor distinctly shorter than metasoma (less than 0.25 × metasomal length). However, it differs from O. srilankiensis in the following combination of characters: body size larger, 6.30−6.5 mm in length (4.00−5.75 mm in srilankiensis ); head and mesosoma black with metallic green, blue, purple and coppery in different parts (dark blue to blue-green in srilankiensis ); head 1.70 × as wide as long (1.28−1.48 × in srilankiensis ); head width 4.20 × eye distance (3.44−3.85 × in srilankiensis ); corona 3.10−3.40 × as long as wide, with structure interrupted (3.70−4.75 × as long as wide, with structure continuous in srilankiensis ); mesoscutellum almost entirely lineate, finely areolate slightly before frenal line (meoscutellum lineate in anterior third to half, rugulose in posterior half or two-thirds in srilankiensis ); profemur robust, 1.95−2.00 × as long as wide (usually medium to elongated, 1.98 –2.33× as long as wide, in srilankiensis ).

The new species resembles also the Palaearctic species, O. niehuisorum Werner & Peters, 2018 in having the small body size; wings hyaline; eye large; metasoma short; pronotum pentagonal, with broadest part before midlength. However, it differs from O. niehuisorum in the following combination of characters: head with some blue (never with blue in niehuisorum ); antenna with scape red-brown, rest dark brown to black (scape and pedicel (except apex of pedicel) yellow, rest dark brown to black in niehuisorum ); corona thick, 3.10−3.40 × as long as wide, with structure interrupted (medium, 3.80−6.00 × as long as wide, with structure continuous); mesoscutellum normal, sct.l/sct.w 0.60−0.72 (normal to slender in niehuisorum , 0.55−0.85); propodeum large, ppd. l/msc.l 0.17−0.21 (medium to large in niehuisorum , 0.12−2.15); mesoscutellum completely lineate, slightly finely areolate before frenal line (densely lineate in anterior half to anterior two-thirds, and areolate on posterior half or third in niehuisorum ); profemur robust, fm1.l/fm1.w 1.95−2.00 (robust to medium in niehuisorum , 1.82−2.15); marginal vein medium, mav.l/pmv.l 1.95−1.00 (short in niehuisorum , 0.78−0.89); ovipositor short, ovp.l/mts.l 0.13−0.14 (short to rather long in niehuisorum , 0.14−0.18).

Etymology.

From the Latin, refers to the similarity of this species with O. srilankiensis Werner & Peters.
